推荐答案

您的属性文件位于类路径中. java.io.File仅了解本地磁盘文件系统结构.这是行不通的.您需要通过类加载器直接从类路径中获取它.

Your properties file is in the classpath. The java.io.File only understands the local disk file system structure. This is not going to work. You need to get it straight from the classpath by the classloader.

这是一个开球示例:

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
InputStream input = classLoader.getResourceAsStream("/resources/messages.properties");

if (input != null) {
    Properties properties = new Properties();
    try {
        properties.load(input);
    } finally {
        input.close();
    }
}
